That is the class itself, averaged across everyone who taught it. Who taught it, and how each of them scored, is the board below — that is what a student picking a section is actually choosing between.

What the challenge rank is made of

76thMore challenging than 76% of BC classesranked against every one we hold

95BC — “Intellectually Challenging”1 record · raw score out of 100

Boston College's own “intellectually challenging” question for this class only — students answer it positively about courses that stretched them, so it measures intellectual challenge and NOT grading, workload or quality. Almost every BC class scores high on it, which is why it is shown as a rank rather than a score.

What the workload rank is made of

78thMore work than 78% of BC classesranked against every one we hold

60BC — “Workload”1 record · raw score out of 100

Boston College reports workload for this class only as one of five bands, not as a number of hours, and it does not publish what the bands mean — so this site will not translate it into hours. Higher means more work, which is not the same as worse.

Instructor	Overall	Workload	Challenge
Francisco Marmolejo CossioAssistant Professor · Computer Science Provisional	921 record	78th	76th

There is no ranking to read here: Francisco Marmolejo Cossio is the only instructor with evaluation records for CSCI 3100, so the number is a record, not a position. It rests on 1 record, which is thin — read it as provisional.

Workload, difficulty & attendanceNot ratings

WorkloadHow much work the course took outside class, on Boston College's five-band scale — the band boundaries are not published, so this is not a number of hours.

6078th pctl

Intellectually ChallengingThe course was intellectually challenging.

9576th pctl

Attendance MattersAttending class was necessary to do well in this course.

8315th pctl

Bar length is the rank against every comparable record we hold, not the raw score: BC's questions all have a median around 4.5, so a raw-scale bar would be nearly full on every row and would tell you nothing. Every bar is one ink colour — nothing here is graded green or red. The hatched bars are not ratings at all: a higher number on either describes a different course, not a better one.

How to read this boardInstructors are ranked on their record in this class only, never on their average across everything they teach. Scores are out of 100 — Boston College's 1–5 agreement scale, ×20, the way these numbers were printed for years. Workload is BC's own five-band figure, not a number of hours, and is shown as a rank. A dash means the question was not reported, and is never a zero.
